So the weather in Italy and Switzerland will be a bit schizophrenic. It will be in the 60s/70s for parts of our trip (Rome and Sorrento), 50s/60s for other parts (Florence and Venice) and potentially rainy or at least damp (Venice and Basel, Switzerland). So for clothes, its all about the layers baby.
I'm mixing and matching these shirts with a black dress, one pair of jeans, one pair of black pants, a black cardigan, a pink sweater and two scarves. Red paisley goes with stripes, right?
